Facts about VOLCANOES

Hello!!! I'm Mateo and I'm going to show some facts about a volcano:

Did you know???

The name "volcano" has its origin from the name of Vulcan,a god of fire in Roman mythology.

As gas in the molten rock builds up it needs to escape somewhere. So it forces its way up through fissures which are narrow cracks in the earths crust. Once the magma erupts through the earths surface its called LAVA!!
